The mushroom is a uncommon species only fruits in Autumn on the mixed forest floor. The color of the gills are so uncommon,but i can not name it. Would you please give me some help?

In my books, Gymnopilus spores can vary from “yellow rusty” to “rusty brown”, and I’m not proposing any particular species here.
The second picture shows yellowish gills that initially are spotted red brown, finally completely brown, something I don’t recognize in any other genus – but I have settled for “Could be” because I don’t know every species in the world..

Erin, let’s hear a better suggestion, and I might even support it ;-)

Hmm, I took a look at the first photo, and it is hard to tell whether there is thick spore deposit on the underlying cap or if that is just the colour of the pileus. However, if that brown area under the cap are spores, then I still don’t think the colour is right for Gymnopilus. Here are two photos of Gymnopilus with heavy spore deposits, and the typical rusty orange spores I would expect of the genus:


Why Gymnopilus..

I looked closely at the lower cap in the first picture, and I beleive there are rusty brown spores, fallen from the cap above. Some Gymnopilus species (penetrans/sapineus for example), have gills that are strongly discolouring to brown. Slightly fibrillose cap (possibly veil remnants on the cap margin too), remnants of a white veil/cortina on the stem. That’s about all I need to make a guess..

Irene, why Gymnopilus?

If you view the full size image you’ll notice a light spore deposit on the stipe where the annulus would be, and if you look at the lamelle, it appears that the spores are probably light coloured, maybe white, tan, yellow, pink, buff, light brown, or something along those lines. If it were Gymnopilus I would expect to see distinctly rusty orange/brown spores or gills. Sometimes with excessive rain or advanced age the spores will be long gone, but these don’t look that old, and I do see spores, they just are not the right colour for Gymnopilus.

macroscopically, it resembles a honey mushroom…

the stipe looks pretty tough; does the outside peel off to leave a soft center? the cap fits, too. and I have seen honeys with dark gills here in CA. honeys are notoriously changeable and tricky to recognize, and there are terrestrial as well as wood-dwelling forms.

spore print is key, tho. keep us posted!

Thank you! I will

If yu find it again, make sure to take a spore print. I really haven’t got a lead on this mushroom, but perhaps someone else will.

what a pity that no spore print was done.

Interesting gills, indeed. Did you get a spore print?
